Is Boston Market Zucchini And Squash High in Histamine?

Boston Market Zucchini and Squash

High histamine

Boston Market Zucchini and Squash is high in histamine because of the vinegar in its dressing.

Food here is usually assembled to order from components that were prepped earlier in the day, so it tends to be fresher than a drive-through and less fresh than cooking at home. Histamine builds up as protein foods sit, so how long the chicken or beef has been in the warmer matters as much as what is in the bowl. Treat the rating above as a starting point.

This is zucchini and summer squash cooked in a dressing of soybean oil, vinegar, cider vinegar, olive oil, onion, garlic, and mustard seed.

The vinegar: it rates high and is part of the cooking liquid, which is the main reason this side now lands high.
Cider vinegar and soybean oil: these each run moderate, adding to the vinegar, while the squash, onion, and garlic themselves are gentle.

A plain steamed vegetable side without the vinegar dressing would sit lower.
